Fanatic in middle of boozers, unusually late getting round in (6)
I believe the answer is:
zealot
'fanatic' is the definition.
(thesaurus)
'middle of boozers unusually late getting round in' is the wordplay.
'middle of boozers' becomes 'z' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'unusually' indicates anagramming the letters.
'getting round' becomes 'o' (I've seen this in other clues).
'in' indicates putting letters inside.
'late'+'o'='lateo'
'lateo' anagrammed gives 'ealot'.
'z' put within 'ealot' is 'ZEALOT'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for zealot that I've seen before include "Fanatic person, much too enthusiastic" , "Fervent partisan" , "Fanatic, obsessed person" , "Fanatic for a cause" , "One ardent for cause" .)
